An old stone building in the village may be the remains of a medieval chapel. The eastern half was pulled down in the 19th century, but a wall survives as part of a garage and includes part of a medieval doorway and window. (1)

The remains of an ancient chapel, in the middle of Headlam village, had been converted into a stable by 1857. The eastern half had been pulled down a few years previously and all that remained then was the fragment of a pointed doorway and a small window with semi-circular head, formed out of stone. On the steps leading to an adjoining granary were some stones which had formed the jamb of an ancient door or window.In 1973 it was reported that the stones on the granary steps were missing. The building of which the wall containing the window forms a part was then a garage. (9)
